why most governments did not implement NDCs aggressively at 2015 Paris agreements?
A pair of studies in Nature found that as of 2017 none of the major industrialized nations were implementing the policies they had pledged at the 2015 Paris agreement, and none met their pledged emission reduction targets, and even if they had, the sum of all member pledges (as of 2016) would not keep global temperature rise "well below 2 °C".
most governments have done very little towards implementing the NDCs at 2015 agreements. James Hansen, a former NASA scientist and leading climate change expert, voiced anger that most of the Agreement consists of "promises" or aims and not firm commitments and called the Paris talks a fraud with "no action, just promises"
I am just very curious to know why didn't they implement the NDCs aggresively?
According to the 2020 United Nations Environment Programme (UNEP), with the current climate commitments of the Paris Agreement, global mean temperatures will likely rise by more than 3 °C by the end of the 21st century.
In 2021, a study using a probabilistic model concluded that the rates of emissions reductions would have to increase by 80% beyond NDCs to likely meet the 2 °C upper target of the Paris Agreement, that the probabilities of major emitters meeting their NDCs without such an increase is very low.
question : what was the Reason for most governments not converting their pledges into concrete action at the 2015 agreement,in regards to coal reduction.
(even context of climate finance,reducing emissions from transport,investing in solar energy, would be appreciatable etc)
NDC-NDCs are national climate plans highlighting climate actions, including climate related targets, policies and measures governments aims to implement in response to climate change ex:limiting emmisions within 1.5 celsius
